Carbde grade KR855 is with 10% corrosion-resistant binder with submicron grain structure. Very good wear resistance with high edge sharpness but less shock resistance than higher binder grades. Excellent for EDM operations and good in non-ferrous applications.

KR855 is an upgrade to standard 10% submicron grades, KR855 presents ideal wear resistance in high-speed stamping, medium, thin sheets — coining brass (~.010'' / 0.25mm thick), can die ironing rings, non-gummy steels, compacting dies, stamping dies for razor blades, lead frames (thin copper ~.030''/0.76mm), annealed copper, and draw dies (300 series stainless steel).
